Any of you folks with freshwater aquarium experience, I need your help! OK, so I've had my tank for about two months, and it was finally cycled. Well the last week or so, I noticed the filter pack (the three layers of filter) kept floating up and popping the top off the filter system, right? So I took the filter pack out and examined it, and discover that the bottom of it was covered with a layer of dark green-brown slime, that smelled like rotting vegetation. Several of the plants in the tanks had died, and got sucked into the filter. So I took the filter into the bathroom and rinsed the slime off. Then I decided to clean the whole thing, and I took each of the filter layers out (sponge, charcoal, and ceramic) and rinsed each one under the taps. As I was putting the thing back together and putting it back into the tank, it hit me.... I just rinsed the majority of my bacterial cultures down the ^&*$%^* sink!!!! So have I killed my fish? I have a bottle of that bacteria booster stuff, so I quickly added that the tank, and poured a little directly into the filter. Is this going to cost me all my fish? What should I do? IS there anything I can do???
